I have this problem too.. Windows XP Pro SP2 - all updates AMD AthlonXP 1600+ on Shuttle AK31 Rev. 3.1 VIA KT266A Chipset, 512 MB DDR-266 Creative SB Live PCI, Network Card, TV-Card, DVD-ROM, DVD-RW, 2xHDD, FDD, 1xUSB used, Gainward GF5900 AGP VIA 4in1-Driver 4.56 First I thought it was a problem about my ram, but memtest didn't find anything. My next choice was the power supply - a 300W one.. a new one is ordered and iam waiting for it. Because of I have to wait for my new ps I looked a bit around and the next thing I suspected to cause the problems was the NoExecute Feature of the built-in Windows SP2 Firewall. I switched it off in the boot.ini - because the CPU doesn't have this feature. No changes from this, but a good feeling to know it's disabled Problem: Machine Check: Regs (sometimes without Regs) on every cold boot. Some crashes in unspecified situations like listen mp3s and surfing the internet, using Trillian (ICQ,MSN,Yahoo) and so on.. Since I have changed the case to a Chieftec Big-Tower with proper cooling abilities, I haven't had any crashes - hope this is going on this way. BTW, I don't think it's the best way to disable the MCA feature, but that's an everyone´s selfmade decision. Results: bad RAM - no bad PSU - maybe for crashes, but not for Machine Check "Information" bad CPU - no, everything was fine until SP2 bad VIA Driver - maybe, has anyone checked it with older drivers ? (to avoid the crashes and/or the Machine Check thing) If I find any other issue to solve the problem, I will post it here. @bo_bo: If you find no Event for this (i never did) it's an error that occurs in the hardware or in a high kernel level. If it is anything else, Windows will give out a BSOD/reboot, and you have the Event for a saved Minidump to check. AFAIK.. Best regards mainhack
